Write the balanced formula, complete ionic, and net ionic equations for the reactions that occur when the following are mixed. a. potassium hydroxide (aqueous) and nitric acid b. barium hydroxide (aqueous) and hydrochloric acid c. perchloric acid [HClO4(aq)] and solid iron(III) hydroxide For all of the above, show each step you took to arrive at the total and net ionic equations.
Calculate the mass percent of magnesium chloride in the mixture. Determine the minimum volume of silver nitrate that must have been added to ensure complete formation of the precipitate.
What is the maximum efficiency of a steam engine operating between 20° C and the boiling point of water, 100 °C, at one atmosphere?
What is the required flow rate of cooling water to the exchanger between the wasteheat boiler and the absorber and how much heat must be removed by the two heat exchangers cooling the recycled absorber liquid? Why is there a need to remove this heat?
A 1 m^3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum.
The following sequences of reactions are to occur in a constant density reactor. Which type of continues flow-reactor would be best to maximize the selectivity for product C?
Into a barrel containing 33.2 bbl (US) of water containing 0.0012 mol/L of a blue dye you pour V2 yd3 of water containing 8.91 M of the dye. The final concentration of the dye in the barrel is 7.91 mol/m3 after it's well-mixed. What is V2 is yd^3?
The scaling factor k must be such that the total probability is one. Therefore, we have k = 1/36. The table shows one instance where x + y >5, which is x = 3, y = 3. The probability is p = 9/36 = 1/4.
Draw another diagram overlaying the Pourbaix diagrams for nickel and silver and use this diagram to explain the likely outcome of holding a solution of nickel ions in a silver container.
A mixture of ethanol and benzene is separated in a network of distillation and membrane separation steps. In one intermediate step, a near-azeotropic liquid mixture of 8,000 kg/h of 23 wt% ethanol in benzene is fed to a pervaporation membrane cons..
